BACKGROUND<\/strong>
\nVitamin K1 is a nutrient in green leafy vegetables; deficiency may promote coronary artery calcification. Warfarin, an anti-coagulant used in secondary prevention of thrombotic events, is a Vitamin K antagonist. Thrombotic and coronary events may share risk factors.<\/p>\n

OBJECTIVES<\/strong>
\nTo clarify the role of vitamin K1 in ischemic heart disease the risk of coronary artery disease\/myocardial infarction (CAD\/MI) was assessed according to genetically determined vitamin K1 levels. Given, vitamin K1 is fat-soluble associations with lipids were similarly assessed to assess pleotropic effects via lipids.<\/p>\n

METHODS<\/strong>
\nSeparate sample instrumental variable analysis with genetic instruments (Mendelian randomization), was used to obtain an unconfounded estimate of the association of vitamin K1 (based on rs2108622 (CYP4F2), rs4645543 (KCNK9) and rs2192574 (CTNNA2) from a genome wide association study) with CAD\/MI using CARDIoGRAMplusC4D (cases=64374 controls=130681) and with lipids using Global Lipids Genetics Consortium Results (n=196475).<\/p>\n

RESULTS<\/strong>
\nVitamin K1 single nucleotide polymorphisms were positively associated with CAD\/MI, odds ratio (OR) 1.17 per unit (nmol\/L) of natural log-transformed genetically predicted vitamin K1 , 95% confidence interval (CI) 1.08 to 1.26, but not with inverse normal transformed low-density lipoprotein cholesterol (-0.0003, 95% CI -0.03 to 0.03), high-density lipoprotein cholesterol (0.02, 95% CI -0.01 to 0.05) or triglycerides (-0.01, 95% CI -0.04 to 0.02). Considering only rs2108622, which is functionally relevant to vitamin K1 , the association for CAD\/MI was stronger (OR 1.21, 95% 1.08 to 1.36) CONCLUSIONS: Vitamin K may cause CAD\/MI, whether vitamin K or other determinants of coagulants could be relevant to primary prevention might bear consideration.
